XC18V master parallel configuration

[Matthias Müller]

Hello,
I have cascaded two Xilinx PROM's: XC18V04 + XC18V512 in order to
configure a XC2VP7 in Master-Parallel mode. Impact 6.2i only offers the
option Xilinx Serial PROM. Also if I use the non xilinx-specificl option
"Parallel PROM" it seems not to be possible to run the PROM's for
paralle configuration! I can only configure the FPGA in Maste serial
mode! Does anyone know how I can run the cascaded PROM's in
Master-Parallel mode?
Thank you,
Matthias

The parallel mode of the XC18V00 series is set during
configuration, not at the time you generate the PROM file. You
would therefore select the parts during PROM file generation as
if you were using them in the serial mode. Then when you configure
the devices over JTAG, right click on the XC18Vxx parts and check
the Parallel Mode box in the programming options.

Matthias,

You'll still generate the Xilinx PROMs with teh Xilinx Serial PROMs
option. To program the FPGA from the prom in Parallel mode, you'll have
to set the option when you program the MCS file to the PROM.

After you've generated MCS file from the Xilinx Serial PROMs option, you
should detect the JTAG chain. You'll then proceed to assign the MCS file
to the PROM. If you then right click on the PROM and select Program, a
program Options dialogue would pop up. To the right of the dialogue box,
you'll see options such a Load FPGA or Parallel Mode. If you check the
Parallel Mode option, the PROM will configure the FPGA in parallel mode.
